It’ll be easier to figure out why there’s a DHCP Timeout/Failure, the log it sends to my computer, might say something about it.
Also, I can easily see who’s trying to connect to my AP now too. It also shows the group key completed handshakes. That is set low, so the log will be flooded with that.
It wasn’t working, because UniFi uses UDP, I used the config from Arch Linux’s Wiki, and it was set to TCP. Changed it to UDP, and the firewall rule, and now it works.
syslog-ng isn’t running as root, I edited /etc/default/syslog-ng@default. The instructions on Google, don’t work, you need to add the -u -g options to OTHER_OPTIONS, not add the variable it says to add.
